or cumulative adverse effect on natural erosion processes.
(2)
Sedimentation Control is the ability of wetlands to settle out
sediments and other waterborne material by reducing water flow by
passing it through vegetation or by diffusing flow and reducing velocity.
Activities in or within 100 feet of resource areas shall not significantly
accelerate or impede the rate of natural sedimentation.
FLOOD CONTROL
Is the ability of wetlands to absorb, store and slowly release
floodwaters to minimize peak flood levels. Flooding can be caused
by precipitation or a rising water table. Activities within 100 feet
of resource areas shall not alter the flood control value of wetlands
significantly.
GROUNDWATER

Permitting process to offset adverse impacts associated with the proposed
work to the Resource Areas, or their wetland values under the Bylaw.
MITIGATION PERMIT
A permit which allows the use of land within the buffer zone
under a special exception to these regulations. Any intrusion into
buffer zone setbacks or alteration of buffer zone habitat shall be
considered adverse and shall be mitigated by counterbalancing beneficial
actions which offset these adverse impacts by a minimum of 110%. Issuance
of Mitigation Permits is allowed only in the Buffer Zone Resource
Area and will only be granted after an affirmative vote of three fourths
of the full Commission.
NATURALLY VEGETATED CONDITION
An area on a lot or parcel of land, or portion thereof, that
is left in a natural, undisturbed vegetative state; has existed in
a primarily natural, undisturbed state, but has been or may be enhanced
with indigenous plantings conducive to improved Wildlife Habitat according

not hinder access to coastal and inland resources. Activities that
shall be considered part of the use and enjoyment of our natural surroundings
in a manner consistent with their preservation shall include but not
be limited to recreational boating, swimming and shellfishing. The
Commission's analysis of the project's effect on the wetland
value of recreation should be relative to a proposal's potential
impacts on other protected wetland values, with priority given to
enhancing and protecting those recreational values which are not detrimental
to the continued natural functions of wetlands or their wetland values.

the commonwealth, including great ponds; and tidelands, being present
and former submerged lands and tidal flats lying between the natural
high-water mark and the state limit of seaward jurisdiction. Tidelands
include both flowed and filled tidelands, and privately owned and
publicly owned tidelands.
UNVEGETATED WETLAND RESOURCE AREAS
Are coastal areas, such as flats and unvegetated intertidal
areas; coastal and freshwater beaches, dunes and banks; and land subject
to flooding. Also, inland areas subject to flooding which do not support
wetland vegetation, but which store at least 1/4-acre feet of water
to an average depth of six inches at least once a year, and land areas
two feet or less vertically above the high-water mark of any lake
or pond defined by 310 CMR. Does not include swimming pools, artificially
lined ponds or pools, wastewater lagoons or stormwater runoff basins,
the construction of which may be regulated, but do not themselves
constitute regulated areas.
VALID CONSERVATION PERMIT

294 and these Regulations.
WETLAND DELINEATION
(1)
The procedures used to establish a line connecting wetland delineation
flags and/or applicable test plot which defines the upper limit of
a plant community where 50% or more of the individual plants are included
in facultative (FAC), facultative wetland (FACW), or obligate wetland
(OBL) categories in the National List of Plant Species That Occur
in Wetlands: U.S. Fish & Wildlife Service, U.S. Department of
the Interior, 1988 or plants exhibiting physiological or morphological
adaptations to life in saturated or inundated conditions. In addition
to vegetation a delineation methodology shall include an evaluation
of hydrology and soils using MassDEP's Massachusetts Handbook
for Delineation of Bordering Vegetated Wetlands (Second Edition, September
2022) or the latest edition of said Handbook when the delineation
was accomplished. Wetlands shall be delineated by the applicant's
Qualified Consultant using this Handbook.
(2)
For sites where there is a dispute regarding the location of
the delineated wetlands line, the delineation shall be redone using
the methodology according to the U.S. Army Corps of Engineers Wetlands
Delineation Manual dated January 1987 (Technical Report Y-81-1) as
modified by the Regional Supplement to the Corps of Engineers Wetland
Delineation Manual: Northcentral and Northeast Region, (Version 2.0)
dated January 2012. Based on the scientific evidence presented, the
final decision regarding the location of the delineated line shall
be made by a majority vote of the Commission. When the boundary is
not presumed accurate or to overcome the lack of clear and credible
evidence, additional information shall be submitted to the Commission
by a Qualified Consultant selected by the Commission and paid for
by the Applicant. The submittal by the Commission's qualified
consultant may necessitate the applicant's qualified consultant
to submit additional information. The Commission maintains sole discretionary
authority relative to a determination that a wetland delineation is
accurate.
